Cast your vote and your comments, let's see the average speed in the construction industry for high rise...

No vote?

It depends on many factors.

Factors such as? Say they need complete by 48 months?

1) Type of formwork use
2) Floor area per floor
3) Complexity of the structure
4) Design

This is just for progress of structure works. For architectural works, it normally take around 7 to 8 months from concrete topping up works.

aluminium formwork

But generally, as a person without knowledge on how construction works, what kind of physical sign we should look for to determine whether a construction was slow/fast in progress?

i'm only determine the progress looking at the rate they built up the floors.. please enlighten..

Aluminium formwork usually take around 7 days circle per floor for typical floor.

To judge whether a condominium project is on time or not maybe one can calculate is such a way,

From the SPA VP date, minus 4 month for getting CCC after CPC, then minus 8 months for general architectural works.

Then use this date minus current date, this will be your total month to carry out the structural works. Then use this period divide by total story of your condominium, that will let you judge how many days in average are needed per floor in order to deliver the project on time.

But some floor will take longer time to complete, such as the podium, 1st typical floor, transfer floor, non typical floor and etc.

Hope this help.

i been told some projects can goes as fast as average 4 days per floor,

maybe they during concrete setting time they can do all the rebar and formwork installation for upper floor...

I got the same thought. Say 48 months in SPA for 36 storey, 12months for painting, facilities, architechures and etc. Left 1 month per floor.. haha

Thats fast till scary.. but if compared wih China, thats nothing..

those in china you mean precast system? sure fast lor.... but malaysia not cost efficient yet ler...

Not sure what it called, but I noe is damn fast.. their planning take a lot of time, but construction time is very short..

Fastest i heard before is 6 days in average. 4 days maybe happened once in a blue moon.

From my previous study China those super highrise (above 70 storey), they can achieve 3 days circle in average. Center core is reinforced concrete while others are steel structure with bondeck.

the one in malaysia is concrete cast insitu, if commercial building which use steel structure or precast concrete structure then can even faster la... normal residential in malaysia still using normal method... just faster in terms number of labours, type of formwork used, proper planning, coordination and execution...

and depends they work how late each day....

yes, if they're using IBS where some components are factory prefab then they can go really fast .. .

have done 4 days cycle for approx 17k sf floor plate previously.
shear walls all around no less and no brickwalls.

but not every floor also achieve 4 days cycle lah.

Actually, how to differentiate all these type of walls and its pros n cons?

mr. google is your best friend.

Tried but not much good info..

shear wall... concrete and steel bar

2 types of shear wall

load bearing sheer wall... support of the structure, the shear wall thickness usually depend on the loading need to be taken by the support, lower floor is thicker (e.g. more than 10") and upper floor will be thinner ... cannot be dismantle or hack later the structure will collapse or crack...

non load bearing shear wall... non support of the structure, just normal steel bar inside to hold the wall and very thin in thickness (4"-6")... more popular because increase speed of construction (no need lay bricks), use at small wall like toilet etc...

but you duno which one is load bearing and which one is non load bearing... so all shear wall now they say cannot cannot hack

to get 4 days per floor need every floor is typical floor and typical formwork can be use...
